Recyclable Organic Solar Cell Hits New Efficiency Record at 2.7%

Benji Jerew — Tue, 26 Mar 2013 19:19:20 +0000

Photovoltaic organic solar cells have the potential to be truly green, but often their manufacturing processes are not so green. Petroleum- and silicon-based solar cells can be bad for the environment and nearly impossible to recycle. One possible solution to creating a truly green solar cell could be to use natural materials. On the other […]

An interesting observation on the way wasps live and how their body works led some UK and Israeli scientists to the conclusion that they may be harnessing solar power just like a photovoltaic solar cell.

The first organic solar cell has come from Switzerland. It seems somehow normal that the first practical application and the first organic solar cell manufacturer to come from Germany - doesn't it?

Graphene Flakes With Attached Brushes Improving Dye-Sensitized Solar Cells

Until now, graphene could have theoretically been incorporated into the dye used to make the Graetzel cell to improve its efficiency, but what stopped the scientists to do that was that it always clumped together, forming graphite, which is of no use for a solar cell.

Chemistry Professor Innovation Making Dye-Sensitized Solar Cells More Efficient and Durable

Ovidiu Sandru — Wed, 07 Apr 2010 14:56:21 +0000

Dye-sensitized (Graetzel) solar cells have been in the spot of many minds since they were first created in early ’90s by Michael Graetzel, from EPFL, Switzerland. Until now, dye-sensitized solar cells only proved to be cheap, but also inefficient. New technologies are expected to improve their performances. Graetzel cells work on the same principle photosynthesis […]
